Abstract: A coin counter includes a base unit, an adjusting plate adjustably mounted on the base unit, and a coin outlet port mounted on the base unit. The adjusting plate has a first end provided with an adjusting slot and a second end provided with a micro-adjusting slot. The adjusting plate has a mediate portion provided with a guide slot located between the adjusting slot and the micro-adjusting slot. Thus, by provision of the micro-adjusting slot of the adjusting plate, the pitch angle of the adjusting plate can be slightly adjusted to slightly adjust and control the projecting distance of each of the coins so that each of the coins can be projected onto the coin outlet port exactly to facilitate collection of the coins.

Abstract: A parking meter actuator handle is provided with a breakaway device comprising a detent disposed between first and second relatively rotatable parts. The detent is pre-loaded in a pair of aligned recesses but accommodates displacement in response to a breakaway torque to protect the parking meter against vandalism.

Abstract: Apparatus automatically feeds coins into a parking meter. The timing clock used in the parking meter operates an external coin feeding mechanism to feed a coin when the time on the parking meter is about to expire. The invention is applicable to parking meters of the type wherein the insertion of the coin rewinds the clock as well as of the type wherein a knob is turned to rewind the clock after the coin is inserted. With the latter form of parking meter a special battery powered circuit is employed to wind the clock in increments after a coin has been automatically inserted.

Abstract: A display device which can mechanically and cumulatively count and display the amount of money for coins. The use of coins having a random relation between nominal values and diameters is possible by the provision of operation members. The operation members include carry operation members, each of the operation members has a corresponding digit display wheel which shows the cumulative amount of money. A coin inlet and guide member has pushing members for pushing a suitable operation member without pushing other operation members. To this end, the operation member other than the carry operation member each has at least one groove with a reception surface to which the pushing member abuts for pushing the operation member and an idle groove which is not actuated by another of the pushing members if it is guided into the idle groove. The idle groove serves as eliminating the problem of the random relation between nominal values and diameters of the coins.
